LUBRICATION INDICATOR.

Application filed December 26, 1923. Serial No. 682,703.

My invention relates to devices operated in use. By my invention Iemploy a pluralby or associated with the well known specdity of segmentform tablets, one for each ometer periodically warningor giving n.osignal and its explanatory text which are tice to the driv .r of a motorvehicle of the mounted in an annular space of about the 60 I necessityfor attending to some requirement diameter of the usual cylindricalshell or casof the car at the expiration of certain milcing of thespeedometer, the entire annular ages, and in particular my invention hasto spacebeing if desired equally divided among do with devices of suchkind in which the the tables which thus extend in a com )lete signals orwarnings are distinctive marks, annular series concentric with the speetom- 65 such as different colors, upon the dials or eter and around thesame. Each of these number wheels of the total mileage odometablets isslidable from within the space forter. lVhen a particular color or otherward until it is sufficiently withdrawn to marking is exhibited by adial wheel the mo- P it it to be swung or otherwise moved to toristknows that something should be done a position to expose the readingmatter 70 to or for the car but the color or other markthereon and topermit it to be returned into ing does not in itself give thatinformation such space. but reference must be made to a chart whichferring in detail to what is shown 111 the has the correspondingmarkings or coloring drawings the speedometer illustrated shown to thoseon the dials with a verbal ex lanahas the customary circular form withhorl- 75 tion of what must be done when a particular zont-al slo s inits dial or face plate, 10, for

The small area eter, 11, andthe total odometer, 12, these of the dial wheels precludes anything butbeing of the side by side disk type and the color or other distinctivemark thereon. dials of the trip odometer having at ap- 80 The object ofmy invention is to provide the propriate points upon their peripheryblocks verbal explanatory matter in such a way or spots, 13, ofdifferent colors which at the that it will be instantly accessible,require expiration of the appointed niileage apa minimum of space with amaximum of pear at the display opening and the speedinformation, beunobtrusive in appearance ometer having a cylindrical shell or casing,85

Concentric with and spaced a slight distance 9o Inthe annexed drawings: from the periphery of the shell or casing is Fig 1is a face View of a speedometer ema supplemental cylindrical shell orcasing, bodying my invention; 16, which may be attached to and extendFig. 2 is a detail view in section on the rearwardly from the supportingplate, 15,

Ordiinstrument around the face or dial plate are we narilyfive different colors are used and asslidably mounted edge to edge thesegment sociated with each color is textual matter form tablets, 17,there being preferably beexplaining what must be done when the tween theedges of adjacent tablets a guide color appears and hence there must befive rib, 18, parallel with the axis of the cylindifi'erent items oftextual matter, which may drical shells or casings, to confine the tab-105 comprise a half dozen or more printed lines lets against lateraldisplacement and to each two or more inches long. It is obviguide themin their sliding movement back ously impossible to affix all this matterupon and forth to place them in and out of the the face of theinstrument and a printed storage space between the two shells or chartseparate therefrom is ordinarily a spacing. Each tablet may have at itsfront sheet of such size as to require folding for edge a button, 19, toform a knob or handle placing in the pocket or elsewhere when not formoving it back and forth and such knob may be alone colored incorrespondence with the appropriate color spot on the odometer dial orthe entire front edge of the tablet may be so colored such edge beingvisible at the front of the instrument when the tablet is pushed backinto its storage space. The appropriate textual or explanatory mattermay be on the upper or outer faces of those of the tablets which whenslid out will can pose such faces for ready reading, and upon the upperand inner faces of those Which when slid out will have such facessituated for more ready inspection, it being unnecessary With thisarrangei'nent to swing the tablets when drawn forward out of the annularstorage space to a position that will facilitate reading the textualmatter thereon. To prevent the complete Withdrawal of the tablets a stopfor'each to limit the outward movement thereof is preferably providedwhich may consist of a short round pin, 20, at the front of the annularrecess and a hook form lug, 21, at the rear end of the tablet which willengage the pin and periiit the tablet to be rocked or swung to aposition for better exposing the reading matter thereon as indicated indotted lines inFig. 2. If desired one more tablet than the numbercorresponding with the number of colored spots on the odometer dials canbe provided upon which may be placed a diagram of the chassis showingthe places where lubricant is to be applied and the knob of such tabletcould be White or inscribed with the Word Chart to identify or designateit.

neenara What I claim is:

1. A. device having an odometer with dial markings having reference torequirements of the car Which should be attended to on a mileage basis,the odometer having a suitable casing and a tablet containing textualmatter explanatory of the dial marking shit-table back and forth in aspace adjacent the exterior of the device and which opens at the frontthereof.

2. A device having an odometer with dial markings having reference torequirements of the car which should be attended to on a mileage basis,and a plurality of tablets arranged in a circular group around. thedevice andv slidable backand forth from the face of the device, saidtablets having textual matter explanatory of the dial mark ings.

3. A speedometer having a cylindrical casing and a face plate with aslot for the dis play of the odometer dials, a supporting plate to whichthe speedometer casing is attached having a hole concentric with saidcasing and the odometer dials having distinctive markings and a circularseries of tablets slidably mounted about the speed olneter casing andmovable back and forth through the hole in said supporting plate, saidtablets being provided with textual matter referring to the dialmarkings of the odometer.
